Wall-mounted air conditioning across County Antrim
In a semi or terrace in Belfast, the indoor unit often goes on a back bedroom wall with the outdoor unit on a bracket below. A single wall-mounted unit is often all a bedroom or sunny living room in Belfast needs. Northern Ireland's mild, damp climate makes efficient heating and dehumidifying the main benefits for most homes.
